Module syscall

Task-related system call implementations.

This module implements system calls that interact with task management, filesystem operations, and process control. Many operations leverage the VfsManager for filesystem access when tasks have isolated namespaces.

VfsManager Integration

System calls automatically use the task’s VfsManager when available:

• Tasks with vfs: Some(Arc<VfsManager>) use their isolated filesystem namespace
• Tasks with vfs: None fall back to global filesystem operations
• Bind mount operations enable controlled sharing between isolated namespaces
• All filesystem operations are thread-safe and handle concurrent access properly
